Description

This Astrobin Debut Object, also known as UGC 224, is a pair of galaxies located almost 1 billion light years away in the constellation of Pisces at a declination of -1 degrees.  Each magnitude 16 galaxy spans about 30 arc-seconds in our apparent view, which corresponds to a diameter of 140,000 light years.

In his Arp catalog, Dr. Arp classified this object into the category of Galaxies with Material Ejected from Nuclei.

These galaxies are so far away that it is hard to determine if they are spirals, lenticulars, or ellipticals.  A faint plume seems to surround the pair, suggesting that they are interacting.

The bright distracting star below Arp 201 is the magnitude 8.6 star HD 1944.   I usually try to crop bright stars out of the frame, but this one was too close.

Between the distant dim object and the adjacent bright star, this is one of my least favorite Arp objects.

Many distant galaxies are seen in the background, especially left of Arp 201.  They comprise several different clusters about 3 billion light years away.
